I think the most important point in solving this locked room case...
...is a motive.
Why did the culprit commit murder?
Normally, this question will come up...
...at the time of narrowing down the suspects... or during the substantiation of a crime.
To directly link it to the locked room...
...is usually meaningless.
However, the murder that happened in this room...
...just as this chain lock on the door...
...the motive itself was another piece that created this locked room.
What does this mean?
Let's ponder over this together.
I have a shareholders' meeting with MT Holdings, to go to. I want you to return to the office...
...and start working on the contract's framework.
Yes, I understand.
Excuse me. Can I have a moment with you?
I'm Kono, from the First Investigative Division.
Serizawa-sensei, we would like to ask you some questions.
- What's this about? - You know professional shogi player...
...Takewaki-godan (5th rank*), right? - Yes, of course. (Note: 1st to 9th is lowest to the highest)
The Japan Shogi Association is my client.
Actually, he had been killed in a hotel in Shinjuku.
Killed?
I'm sorry, I'm sure you have a busy schedule but...
..would you mind coming with us to the station?
- I don't mind. - Thank you for your cooperation.
Where were you...
...between 2 and 2:30 pm yesterday?
After my business at the Patent Office, I headed to the Central Asahi Bank's main office.
...I traveled by car. - Do you have anyone who can substantiate that?
There's no one.
Actually, we have examined the call records of the phone in the room...
Takewaki-san had only made one out-going call...
You were the one he called, right, Serizawa-sensei?
- Yes, there certainly was a call. - What was it about?
- It was a personal legal consultation. - About what?
I can't tell you, Detective.
- We have this thing called confidentiality. - Tsk...
...That's a problem.
This incident is a bit troublesome...
...so I'm afraid I may have to question you many many times.
So what do you mean by 'troublesome'?
("Serizawa Go")
Hello, Serizawa-san? It'll be alright.
I'll defend you with all my might, you have my support!
If ever I killed someone, I will never ask you to defend me.
- I knew it, you killed him! - What? I didn't kill anyone!
But you just said!
I said, "IF ever I killed someone."
Listen. I'm just here for the reference...
...not as a suspect. Don't make a mistake.
"Really? Then what was it that he called you up for?"
- Oh, that...uh, it's a fraudulent-- - "Eh? 'Fraudulent'?"
Anyway, I'll have to get this incident solved quickly...
...or else, I'll be in big trouble.
- I want you to contact him as soon as possible. - Him?
The room where Takewaki-godan was killed... it was a locked room.
- Um, excuse me. - Yes.
Can you tell us briefly what happened when you discovered the body?
Yes.
- "Your room number is 604." - "Thank you."
The time Takewaki-sama checked in...
...was around 2 pm. Immediately afterwards, Takewaki-sama received...
...a phonecall, and then at 2:30, there was another one...
I patched the calls to the room but...
...but there was no response to the second call, so I came up here to see.
Do you know who it was on the phone?
Both phonecalls came from a woman named Kurusu-sama...
...And that the police had confirmed that the calls ..
...came from her home in Kichijoji. - So then...
"Takewaki-sama?"
Since there was no response even after I knocked...
I opened the door with the master key but...
...it was held back with the chain.
From the gap in the door, I saw...
...Takewaki-sama lying on the floor and was stabbed in the back.
So I called 110 right away.
When you opened the door for the first time, were you able to open it smoothly...
...without hitting the body? - Pardon?
Oh, since the door was held back by the chain...
...it did not reach the body.
Did the culprit took off with the key?
We believed so...
Normally, that should've been enough...
With the body so close to the door, once the door is opened it'll be discovered...
...then why was it necessary to secure the door with the chain?
If we can figure that out, it'll make things easier...
Excuse me... but can you please try opening the door?
Me?
Thanks.
There's a surveillance camera in the hallway, do you think...
...it has footages of the culprit?
- They're all dummies. - Oh, you already checked it?
I can tell just by looking at it. It's a way to skimp on expenses.
Then what about the front desk. Have they seen the culprit?
This hotel was structured in a way that...
..one can ride the elevator from the first floor without passing through the front desk.
Excuse me...
Kurusu-sama has arrived at the front desk.
Alright.
Here are some belongings of the deceased. As Takewaki-san's girlfriend...
...can you please verify these items?
These are the items Shinpei-san always used for study.
Please...!
...Don't touch anything.
I'm sorry.
What're you ogling at?
I think all the other things are Shinpei-san's, too.
Then, is there anything missing?
- Nothing in particular. - He didn't have a cell phone...
...or a computer? - Yes...
...he didn't have them.
- Do you like shogi? - Well...
...I've dabbled with it.
Oh! You're Kurusu Nahoko-san, right?
...the shogi player. - Yes.
I saw you in the news, you may become the first...
...female professional shogi player. I'm also 26 years old...
Although we're the same age, I thought you were amazing. I'm rooting for you.
Thank you so much.
I'm Aoto from Friedman & Serizawa Law Firm.
My boss Serizawa was...
... consulting with Takewaki-san...
..that's why we're cooperating with this investigation.
- Cooperating with the investigation? - Yes.
He's an expert in solving locked room cases...
Recently, he was able to solve two murder cases consecutively.
- Is that so? - I'm also sure...
...that this locked room, too, will be unlocked.

Special thanks to: furransu, \( -o _ o- )/, mikaljan, honest
Kurusu-san, how are you feeling right now?
Since when have you and Takewaki-godan been dating?
"Just for a few months..."
"Right now, you're in the middle of important league games that influence your possibility of turning pro..."
Yes.
Aoto-san, you have a visitor.
Who is it?
It's her.
Enomoto-san. It's Aoto. We're coming in.
Enomoto-san? Enomoto-san, are you there?
So strange.
- Is this a reproduction of the room? - Oh.
- That's correct. - Enomoto-san, where were you?
If the purpose of the crime was theft...
...or if he was planning to kill from the start...
...why was the door secured with the chain?
...That's the biggest mystery. - Is it possible to...
...latch the door with the chain from the outside to begin with?
It is possible to latch and unlatch the chain.
To place the chain on the lock, you'll use the thumb turn tool or...
...use an L-shaped, thin metal sheet to unlatch the door from the outside...
...It won't take too much effort. - I see.
Its just that... I don't see...
...any evidence that either of these methods were used.
I got it. Before the crime happened...
...the door was already secured with the chain.
Then how was the culprit able to leave the room?
He escaped through the window.
The windows are of the fixed type. You couldn't open nor close it.
Then, when Shinpei-san opened the door with the chain on...
...could the culprit have committed the crime through the gap in the door?
If so, how did the culprit make Takewaki-san turn his back?
For example...
...when Shinpei-san opened the door...
...the culprit dropped something on the floor, something that's very important.
So then, when Shinpei-san was trying to pick it up...
..could the culprit stabbed him from above when he bent down?
Please hold on a minute.
If Takewaki-san opened the door with the chain on...
...it indicated that he didn't know who the person was...
...or he was someone that he should take precaution with.
To show such an unguarded state to someone like that...
...is a bit inconsistent.
Moreover, the culprit fled after he locked the room.
How could he have gotten the key through the narrow gap?
So then, without using a key, could he have picked the lock?
...Maybe he was able to lock it from the outside with that. - But then...
...that will not explain as to why the key disappeared.
Then, what if he removed the chain from the outside, entered the room and took the key?
Now, we are back to square one... Although the culprit was able to commit the crime through the gap in the door...
...the chain had to come off again...
I see.
Serizawa-san, thank you for waiting. This is Takewaki-san's--
Ah. Kurusu... you're Kurusu Nahoko-san, aren't you?
Oh, my... I saw you on TV but you're more beautiful in person.
- Please have a seat. - Sorry for this sudden meeting.
Not at all.
What're you doing? Sit down.
I'm sorry but as a lawyer....
...I cannot possibly answer that question.
But whatever his issue was, it might be holding...
...a clue that could help identify the culprit.
Couldn't you tell me what you discussed with him during the consultation?
- Yes. But that's... - Please.
Somehow, I must find out...
...the culprit that killed Shinpei-san.
- Actually, Takewaki-san... - "This way, please..."
Ah, it's impossible for me to talk about it.
- Weren't you going to say it just now? - What're you talking about?
You'll spill it if the person is beautiful, won't you?
- Of course not. - Oooh, is THAT right?
- Enomoto-san. - Thanks for waiting.
I wonder who the killer is.
Anyway, you said before that you're only interested in locked rooms...
...so why the sudden change in interest? - Oh~.
Is it over there?
I guess not...
(Ryu-oh Tournament, 7th match)
For this locked room, motive is something that's strongly involved.
- 'Motive'? - Without it...
...I don't think I can solve this mystery. So I'm here to gather some information.
It'll be alright. Don't worry.
I can do it. So can you...
...Mari-chan. Let's go up together no matter what.
Oh.
I'm sorry. We were looking for the venue and we got lost.
Is that so? Let's go together then.
I'll go wash my face and then I'll follow.
Oh, she's Inagaki Mari-san. She's a junior member of Shorei-kai* (*Association of promising young players, up to 3rd rank)
Since Shinpei-san was killed, she felt sorry for me.
I think she's shaken up by it more than me.
Professional Promotion Match, Third Rank League's 17th Match
- What's happening with Kurusu-san? - She's trapped in a corner.
The next move will decide the outcome.
- "Hey. Look at that." - "This is it."
- Is she okay now? - Yes.
Kurusu-san...
...winning one more round will confirm your promotion to 4th rank*, isn't it? (*professional level)
In this world of the game, no one knows what can happen so I shouldn't be careless...
...and must stay alert til the end... - She's incredible, isn't she?
"Looking back to the game so far..."
"...what are your thoughts?"
Hey! Stop staring just because she's cute!
"As I play each round..."
"...I felt that I was able to grow."
Enomoto-san. That would be Nakano Shuya-yodan (4th rank).
He was supposed to have competed against Takewaki-san...
...on the day after he was killed.
In the end, he won by default, huh?
- Did Nahoko-chan win? - Yes.
Since Takewaki-san was killed she had been getting more and more attention.
Although he was able to win 8 consecutive wins in the Ryu-oh* Tournament... (*means "Dragon King")
...Busujima-ryuoh (title holder) is not getting much attention...
...I feel sorry for him. - What is a 'Ryu-oh Tounament'?
What, you don't know? It's the title match between the world's best shogi players.
Come to think of it, I've seen reporters watching the broadcast in the waiting room.
- Was it via broadcast satellite or something? - Yeah. They'll only broadcast it...
..during the morning and evening hours. - Seems everyone was looking...
...at the computer. - They were reading the next moves...
...using a Shogi software. - "Shogi software..."
Cyber shogi 'Gekisashi,' haven't you heard it?
It's not uncommon for a computer to predict...
...a title match's clever moves ahead of the players.
But during the Ryu-oh's match the other day, the '1-6 Kei' move Busujima-ryuoh made...
...'Gekisashi' wasn't able to predict it.
- I didn't kill him. - Eh?
I told the police, too...
..that I wasn't the only one who had a grudge against Takewaki.
Do you have anyone that comes to mind?
For example, Tani Jiro-hachidan (8th rank - very high). He was furious when Takewaki...
...criticized him by name in a column in a Shogi magazine.
It's because Shinpei-san is very...
..fastidious when it comes to shogi.
So this Tani-san's a great player?
He's a big-shot alright. He gives lectures and stuff...
..on the Shogi channel.
Thank you.
Takewaki-san didn't seem to have had a cell phone?
Yeah.
Oh, come to think of it. He may have had one at some point.
- Eh? Takewaki-san had a phone? - Yeah.
Nahoko-chan, when the three of us went out drinking...
...didn't he flaunt it? - Did he?
I don't remember, maybe I was too drunk.
Enomoto-san, do you have a girlfriend?
A girlfriend... Do you have one?
Does that have anything to do with this case?
Well... About Takewaki-san's cell phone...
Don't you find it strange that Kurusu-san didn't know about it?
Although they may not have had a long relationship...
...don't you think he would've told her the number? - So how is that...
...related to my having a girlfriend?
And I don't feel good about Takewaki-san...
The reason he was consulting Serizawa-san...
...it sounds something that's fraudulent, too...
So how is that related to my having a girlfriend?
I'm just asking what Enomoto-san would think if you were in the same situation.
I mean, can't I ask something unrelated to the incident?
- That's not what I'm saying... - So...
...do you have a girlfriend? Or not?
Why do women...
...like to talk about romance?
Of course, because it's interesting!
- 'Interesting'? - And based on the kind of romance you've experienced...
...you can see the personality of that person.
I don't think it's a subject that's nonchalantly discussed with others.
Why're you being so formal? Enomoto-san, if all you're gonna....
...talk about are locks and security, you won't be able to have a girlfriend.
Huh? Did I go off topic? What was I talking about?
Oh, right. The cell phone.
I wonder if Kurusu-san and Takewaki-san were really dating?
Right now we're deciding between Bangkok and Singapore.
If it's Singapore, there will be tax incentives...
...so I'd recommend it. - I see.
Of course, having the tax incentives or not...
...will make a big difference in profit.
Let's make a proposal for Singapore for the next Board of Directors' meeting.
If it's Singapore, please count on us.
So, Serizawa-sensei is still maintaining confidentiality, isn't he?
Yes. I'm sorry I can't help you on that.
It's alright. I think it is the right thing to do as a lawyer.
And I... decided to...
...focus on the last match right now.
Of course. This is your last chance...
...it should be your first priority.
By the way, you were really cool on that last match.
I'm sure you'll win tomorrow as well. I'm rooting for you.
Thank you. I'm really happy.
Uh. To celebrate your turning pro...
...can we go to a nice restaurant together one day?
I want to become strong.
Both physically and mentally...
...women can't compete with men... I wanted to make those who think that way...
...to eat their words. That's why I chose the path to become a pro.
But the reality is harder than I thought.
With the matches against male players...
...I kept losing in the close matches in the end, no matter how hard I tried.
It so happens I'm in good shape this season, but I might not be in the next.
I'm always feeling fearful about it.
I'm sorry. I'm suddenly talking to you about my troubles.
Not at all. It's just that...
I'll be fine. Still...
...I know I have no choice but to continue.
I didn't kill him.
There are many people who held a grudge against Takewaki... ("Shogi Channel Recording Studio")
...wishing him dead. Isn't Busujima-ryuoh one of them?
- Busujima-ryuoh, too? - Once they were rivals...
...while one was in the limelight...
...the other was killed in some cheap hotel.
On the day that Takewaki-san was killed, Busujima-ryuoh was...
...having a match? - That's right.
So Busujima-ryuoh wasn't considered a suspect.
- Tani-sensei, please. - Yes. If you'll excuse me.
Thank you.
It seems the more we investigate, the more suspects are coming out.
"Ah~, here's the move on the match of the 23rd."
"Busujima-ryuoh's '1-6 Kei' move..."
"Ah~, to move the 'kei' (equivalent to a knight) to the edge is a very risky move..."
"Normally, it does not work well."
"No one, not even the commentator nor the reporters could've predicted it."
"This was such an unorthodox move, it took Kito-kudan (9th rank) by surprise."
Let's go home.
Enomoto-san?
Excuse me. Do you know what time the '1-6 Kei' move was done?
It was at 2:10.
I see. So that's how it happened.
- Could it be...? - Yes.
The locked room has been unlocked.
Please tell us. How did the culprit...
...place the door chain from the outside? - The culprit wasn't the one...
...who placed the chain. - Then, it was...
Also, it was not chained from the beginning.
After getting stabbed in the back...
...Takewaki-san himself had placed the chain.
- Why? - Because he thought...
...the culprit would come back.
He would come back after leaving the room?
That's right. And sure enough the culprit did return.
How in the world would you know that?
I restored the door chain that was disconnected and had someone open the door...
It stopped at the exact spot before it could hit body.
The angle of the door...
...and the angle of the body were exactly the same.
At first, I thought the hotel staff moved the body...
...when he opened the door for the first time...
"Since the door was held back by the chain..."
"...it didn't reach the body."
In other words, before the hotel staff came...
...someone else had tried to open the door.
So he put the door chain because he knew the culprit would be back.
- No. It was the magnet board. - What?
To be precise, it was the move of the Ryu-oh Tounament.
That is what Takewaki-san was trying to protect.
'Ryu-oh Tounament...' What's that?
Because this is a very important clue that will lead to the culprit.
On the magnet board, Busujima-ryuoh's move...
...the '1-6 Kei' was re-produced.
That move was made at 2:10 pm.
Takewaki-san checked into the hotel at 2 pm.
So how did Takewaki-san find out the '1-6 Kei' move?
- Maybe he saw it on TV? - The Ryu-oh Tounament was only televised...
...during the mornings and evenings. - Or someone told him...
...over the phone? - According to the phone records...
He got 2 incoming calls from Kurusu-san and placed one outgoing call to Serizawa-san only.
Kurusu-san's first call came before the '1-6 Kei' move was made.
And there was no response for the second call.
Did he mention to you the Ryu-oh Tounament, Serizawa-san?
No.
To watch it live over the internet, he must have a computer or a cell phone.
But if he had a laptop, he can watch the title match's board with it...
...and he wouldn't be needing a magnet board.
Also there was no space for a laptop...
...neither on the table nor inside Takewaki's bag.
In other words, there's no other way to look at it except he had a cell phone.
I heard Takewaki-godan didn't have a cell phone, right?
Actually, Nakano-san had seen...
...him with a phone somewhere. - Takewaki-san...
...secured the door with the chain to protect the Ryu-oh match's board.
In order to leave a dying message...
...telling us that the culprit took his cell phone.
Do you have an idea who the culprit is?
I have something to show you.
What is this?
These are the moves Inagaki Mari-chan -1 kyu* made in the league's matches. (*grade before reaching ranking stage)
Oh, she's pretty, huh?
Out of those matches, I chose and analyzed the ones wherein she barely made it...
...or those she won at the last minute.
Towards the end of those matches, 90% of her moves were...
...the same as the moves chosen by Cyber Shogi Gekisashi.
Although there are limited moves you can make towards the end...
...I think this number is too high.
So you mean, she cheated somehow?
There was another person who recorded a number that's nearly 90% as well.
Who was it?
Furthermore, those matches that were decided by whether to checkmate or not...
...I analyzed those with 'Gekisashi.'
On the right are her moves. On the left, are the moves picked by 'Gekisashi.'
There were more than 20 moves in total.
What're you trying to say?
If these two people cooperated with each other in order to cheat...
...then everything adds up perfectly.
There's no way that's true!
But her performance for this year is too different from last year's.
Anyone can have his ups and downs!
Please listen calmly. During the game...
I think they were able to cheat using a cell phone.
And that was the phone that was taken away...
...from the scene of the crime. - Please that's enough.
...I don't wanna hear anymore. - We have to listen to it until the end.
Aoto... Hey!
Professional Promotion Match, Third Rank League's Final Match
Please begin.
("Will the first female pro-shogi player be born today?")
- Serizawa-san, where're you going? - I'll be right back.
Hello. Are you leaving?
Kurusu-san has been cornered, huh?
I...
...wanted Kurusu-san to win fairly.
I really believed you will win.
Thank you. And thanks to you, I fought with my own ability and lost.
And now, I can never become a professional.
What's wrong with not being a professional?
It's an incredible feat that you've reached this far.
Don't talk as if you understand how I feel.
A woman like you, brandishing the soundness of your argument...
...It's so annoying.
You went on to becoming a lawyer without any problems...
...how could you possibly understand how I feel?
Do not patronize me.
Please don't be mistaken... I don't think of you as my friend.
It's just that I wanted to know what Takewaki talked about...
...with Serizawa-san.
May I have a match with you?
I'll be honored.
Takewaki-san noticed that you were cheating, didn't he?
That man could sense those things very well.
You had been blackmailed by him and was forced to become his lover.
"Lover"? More like his personal call girl.
Takewaki-san confiscated...
...your cell phone as evidence of the cheating.
- "This is nice, right?" - "Yeah."
"When I saw this, I had to have it."
The information taken from the Gekisashi...
...was relayed to me through that cell phone.
The code can be deciphered in the number of ring tones.
The phone was set on vibration mode and wrapped in sound absorbing material....
...and was placed inside my bag.
I would feel the slight vibration in my knees and hand.
If Mari-chan didn't become 'Sho-dan' (1st rank) by age 21...
...She must leave Shorei-kai.
Both of us were clutching at straws.
If the fraud comes out in the open, both you and Inagaki-san will be...
...permanently banned from the world of shogi.
You had to retrieve the phone which is evidence, by any means.
That is why...
...you killed Takewaki-san, right?
I do have an alibi.
"Who was on the phone?"
"Both calls came from a woman named Kurusu-sama..."
"...they came from her home in Kichijoji."
Those calls were made by Inagaki-san instead.
Then, how was the door chained from the inside?
After you stabbed Takewaki-san...
You took the cell phone and the key and left the room.
You locked the door, and got on the elevator.
And at one point, you left the hotel.
Then, when you realized that you've left an important evidence...
...you hurriedly went back.
But the door was being blocked by the body and you couldn't open it.
You desperately pushed back the body but...
Knowing that you would return, Takewaki-san summoned up...
...his last strength and placed the door chain.
As long as the '1-6 Kei,' a move from the current Ryu-oh match, remains on the board...
..someone will realize there was a cell phone with him.
And since you are the owner of the phone...
... it can prove that you were the culprit.
Wouldn't they think that the '1-6 Kei' was thought of by that man himself...
...and it just so happens that it was on the board?
A move that no one... the commentators, the reporters...
...and not even the top professional players can predict?
Moreover, you yourself did something that was close enough to be seen as a confession.
When was that?
At the crime scene... the first time we met.
"Please... do not touch anything."
"I'm sorry."
At that time...
...Rather than placing back the piece on the board...
...didn't you put it on the table?
This action put the board to the position before the '1-6 Kei' move....
In other words, it went back to...
...the position before Takewaki-san's check-in.
I guess I couldn't overcome my weakness of slacking in the end.
But let me tell you one thing.
I didn't lose to that man.
He just took advantage of the mistake I made...
...for not paying attention to detail.
That's why, I..
...lost to Busujima-ryuoh.
Somehow, I feel a burden has been lifted.
What was I clinging to... until now?
Checkmate.
I give up.
Thank you very much for your cooperation...
...during the investigation. - If I can help it...
..I don't want to meet with you ever again.
The feeling is mutual.
Hey. Who on earth is this Enomoto?
Hey.
Serizawa-san, how far did you know?
- About what? - About Kurusu-san.
Did Takewaki-san ask to consult with you about the fraud?
- Oh. That? That wasn't it. - It wasn't?
Actually, Takewaki-godan...
...had received a large amount of fraudulent claims from porn sites.
I don't understand why he didn't say it!
What does that have to do with confidentiality?
Wouldn't it have been better if he just quickly told about it to the police?!
That's what I really wanted to say but...
But I'm a lawyer, too, so I kept my mouth shut...
Will you teach me how to play Shogi, please?
So we can play together, it'll be fun.
No thanks. I rather play against the computer since I don't have to hesitate.
I'm thinking of offering Kurusu-san to defend her in court...
...although she may refuse...
Aoto-san, do you have a boyfriend?
What kind of romances have you experienced so far?
What's with you?
Nothing. I guess I'm just trying to discuss something interesting.
"Why do women..."
"...like to talk about romance?"
"Of course, because it's interesting."
Nevermind.
